ARAD WST Woltman Silver Turbo 300mm Flanged Water Meter

Woltman turbine water meter, 300mm flanged connection, ultra high flow capacity, wide measuring range, heavy-duty industrial design

The ARAD WST Woltman Silver Turbo 300mm Water Meter is an ultra high-capacity bulk flow meter designed for precise and reliable water measurement in large-scale municipal, agricultural, and industrial systems. Utilizing advanced Woltman turbine technology, it delivers accurate performance across extremely wide flow ranges.

Engineered with a unique measuring unit, the meter features only one moving element in contact with water, minimizing wear and ensuring long-term operational reliability. The magnetic coupling system provides stable measurement while protecting the register from environmental exposure.

Constructed with a robust cast iron body and polyester coating, along with stainless steel internal components, the meter is built to withstand demanding environments. It offers excellent resistance to vibration and humidity, ensuring consistent performance in harsh operating conditions.

The 300mm flanged connection enables secure installation in large pipeline systems. The IP68-rated sealed register ensures clear readability and protection against dust and water ingress, while the extended measuring range allows accurate monitoring across extreme flow variations.
